NAME

       XmTextPosToXY -- A Text function that accesses the x and y position of a character position

SYNOPSIS

       #include <Xm/Text.h>
       Boolean XmTextPosToXY(
       Widget widget,
       XmTextPosition position,
       Position *x,
       Position *y);

DESCRIPTION

       XmTextPosToXY  accesses	the  x	and y position, relative to the upper left corner of the Text widget, of a given character position in the
       text buffer.

       In the case of horizontal writing, the position is the origin of the character. In the case of vertical writing, the position is the verti-
       cal origin of the character.

       widget	 Specifies the Text widget ID

       position  Specifies  the character position in the text for which the x and y position is accessed. This is an integer number of characters
		 from the beginning of the buffer. The first character position is 0 (zero).

       x	 Specifies the pointer in which the x position is returned.  The returned position is the distance from the left side of the  wid-
		 get to the left border of the character.  This value is meaningful only if the function returns True.

       y	 Specifies  the  pointer in which the y position is returned.  The returned position is the distance from the top of the widget to
		 the character's baseline.  This value is meaningful only if the function returns True.

       For a complete definition of Text and its associated resources, see XmText(3).

RETURN

       This function returns True if the character position is displayed in the Text widget; otherwise, it returns False, and no x or y  value	is
       returned.
